Rare
Under 5% of wildlife watchers report a Bay Sucker sighting in Madrid on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 274th most-seen of the 457 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January and June
In those months about 10% of wildlife watchers report a Bay Sucker in Madrid on a given day, against under 5% in February–May and July–December, the lowest months.
5th of 7
Of the 7 cities where we can rate Bay Sucker sightings, Madrid ranks 5th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Athens (Greece, about 10%) and London (United Kingdom, about 10%).
Same order: Hemiptera
The closest relatives of the Bay Sucker that you can see in Madrid (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 20%), Leafhopper Assassin Bug (about 20%) and Red Cabbage Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bay Sucker is recorded against all the insects logged in Madrid (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
